No, 21 and 23 are not twin prime numbers. Twin primes are pairs of prime numbers that differ by 2, such as 3 and 5, or 11 and 13.
These are prime numbers of the form p and p+2.
No - co-prime numbers are pairs of numbers which share no positive integer factors apart from 1. Twin prime numbers are a pair of prime numbers with a difference of 2.
The last known twin prime number as of now is 2996863034895, which is part of the twin prime pair (2996863034895, 2996863034897). Twin prime numbers are prime numbers that differ by 2. However, it is worth noting that there may be larger twin prime numbers that have not been discovered yet.
twin primes are 2 prime numbers with a difference of 2 the prime numbers 5 and 3 are twin primes because 5 minus 3 equals 2 so 109 and 111 are not twin primes

Twin primes
The last known twin prime number as of now is 2996863034895, which is part of the twin prime pair (2996863034895, 2996863034897). Twin prime numbers are prime numbers that differ by 2. However, it is worth noting that there may be larger twin prime numbers that have not been discovered yet.
Twin primes are prime numbers with a difference of 2. 11 and 13 are twin prime numbers (13-11 = 2), 31 and 37 are not.
twin primes are 2 prime numbers with a difference of 2 the prime numbers 5 and 3 are twin primes because 5 minus 3 equals 2 so 109 and 111 are not twin primes
Twin primes are two numbers with have a difference of 2 and that are both prime so 101 twin number is 103
Two prime numbers which differ by 2 are called "twin primes".
Because the definition of twin primes is: two prime numbers with a difference of 2. 3 and 5 are both prime numbers, and their difference is 5 - 3 = 2 → they are twin primes.
A twin prime is a prime number that differs from another prime number by two.ex. (5, 7)The numbers two away from 23 are 21 and 25 which are both composite numbers.So in short, no 23 is not a twin prime.
Prime numbers that differ from each other by exactly 2 are twin primes. Examples of twin primes are 3 and 5, 17 and 19, 599 and 601.
